Google Ignores the dots in gmail Id

I really amazed when i am typing my gmail id without dots  by mistakenly. its accepting without dots in my mail id….

I tried with some other combinations also still its accepting then i realized that we can use our gmail id without dots also it was going  to yOur mail..

this is my actual mail id

By mistakenly I typed like this..

Its going to My mail box after that i checked with other one also like the below

Still its going to My mail box ..

wanna try with your mail id !! okay just go to gmail.com and have a look at this with your gmail id..

Google Saying That

It’s important to keep in mind that Gmail ignores the dots from your username when receiving a message, so you’ll get all the messages sent to subbuk@gmail.com, subbu.k@gmail.com, s.u.b.b.u.k@gmail.com and other similar addresses. The requirement to enter the same username you used when you created the Gmail account might have helped you keep the account secure, but it was really annoying.

The change is just for Gmail users only; Google Apps users for domains do require fidelity to the dots.

SMTP Telnet Test

A Telnet test is used for doing diagnosis of your SMTP server. It can confirm whether the Exchange server is processing email correctly and is really the manual way of entering the commands that SMTP servers do when communicating.

It involves establishing a Telnet session from a computer that is not located on the local network to the external (public) IP address of the Exchange server. You need to carry out the test from a machine at home, or from another office. Doing the test from a machine on your own network will produce useless results.

Note: This is NOT a test for open relay.

1. Start a command prompt.

   Either click start, run and type CMD

   or Choose Command Prompt from Start, Programs, Accessories, Command Prompt

2. Type " telnet " (minus quotes) and press enter.

3. At the Telnet prompt, type

   set localecho

   (minus quotes) and press enter. This lets you see what is going on.

4. Still in the telnet prompt, enter the following command and then press enter

   open 111.222.333.444 25

   where 111.222.333.444 is your Exchange server’s external IP address

5. You should get a response back similar to the following:

   220 mail.server.domain Microsoft ESMTP MAIL Service, Version: 6.0.2790.0 Ready at

6. Type the following command in to the telnet windows:

   ehlo example.com

   and press enter (note "example.com" can be anything that isn’t a domain that the Exchange server is responsible for.

7. After pressing OK you should get a response back

   250 OK

8. Type the following command in to the telnet window:

   mail from:address@testdomain.com

   and press enter (again where address@yourdomain is an email address that is not on the Exchange server. Note the lack of space between from and the first part of the address).

9. After pressing OK you should get a response back:

   250 2.1.0 address@example.com….Sender OK

   If you get "Access Denied" or another error message at this point then the remote server has an issue with your server connecting to them.

10. Type the following command in to the telnet window:

    rcpt to:address@yourdomain.com

    and then press enter (where address@yourdomain.com is an address that is on your Exchange server Once again note the lack of space between to and the first part of the e-mail address).

    If you get accessed denied or another message at this point then the mailbox has a problem – full, non-existent etc.

11. After pressing ok you should get the response back:

    250 OK – address@yourdomain.com

12. Now type

    DATA

    and press enter.

13. You should get a response back similar to:

    354 Send data. End with CRLF.CRLF

14. Now you can type your message.

    Enter the following in to the Window:

    Subject: test message

    Press enter TWICE.

15. Next type in some body message, something like:

    This is a test message sent via telnet

    And press enter.

16. Enter a full stop (or period) and press enter.

    You should get back the response:

    250 OK

17. Finally close the session by typing

    Quit

    and press enter.

18. You should get which will return the response:

    221 closing connection

19. You should now have an email with the subject and the body as entered.

Internet Explorer 8 is working very slow..

 

Some users that upgraded to Internet Explorer 8 experience issues with tabs not working properly or taking a very long time to load.  It seems for most users the issue can be attributed to a problem with actxprxy.dll not installing properly during the upgrade.  If you have a similar problem with IE8, fixing the issue is as simple as a running one command.

Just open up an administrative level command prompt and type in regsvr32 actxprxy.dll and hit Enter. Reboot your computer and your tab issue should be resolved.

VISTA Tune up.. vista Performance tweaks

Windows Vista is a great looking operating system with some awesome features, but it can be slow as molasses unless you’ve got a hugely powerful PC to run it. For most computers however, a few quick Vista tweaks can make a massive difference in the speed of Vista for everyday use.

Here’s our list of recommended Vista performance and speed tweaks:

1. Turn off Windows Search Indexing

Windows Vista search indexing is constantly reviewing files on your system to make their contents available for quick searching. This is handy, but can severely impact system performance.
To disable this constant indexing:

• Click Start then Computer
• Right Click the C: Drive
• On General Tab, Uncheck Index this drive for faster searching
• On the subsequent dialog box, Select Include subfolders and files

2. Turn off Remote Differential Compression

Remote Differential Compression measures the changes in files over a network to transfer them with minimal bandwidth rather than transferring an entire file that has previously been moved. By constantly checking for file changes, this service can hinder system performance.
To disable this service:

• Open Control Panel
• Switch to Classic View
• Select Program Features
• Choose Turn Windows features on and off
• Scroll down and uncheck Remote Differential Compression

3. Turn off Automatic Windows Defender Operation

Windows Defender real-time protection against malware continues to run despite having Automatic operation disabled.
To disable this feature:

• Open Control Panel
• Select Windows Defender
• Choose Tools from the top menu
• Select Options
• Uncheck Auto Start at the bottom of the window

 

4. Turn off Automatic Disk Defragmentation

Windows Vista and its always-on defragment feature isn’t really that necessary and can cause system slow down. Just remember to run a defrag manually every week or so.
To disable this:

• Click Start then Computer
• Right Click the C: Drive
• Select the Tools Tab
• Uncheck Run on a schedule

5. Add a 2GB or higher USB Flash drive to take advantage of Windows Ready Boost (Additional Memory Cache)

Ready Boost is Microsoft’s name for using a USB thumb/flash drive to provide some quick access memory the operating system can use as extra RAM. The Ready Boost system can significantly improve system performance.
To set this up:

• Insert a USB Flash Drive (preferably 2GB or more)
• Click Start then Computer
• Right Click the USB Drive in My Computer
• Select the Ready Boost Tab
• Choose Use this device
• Select as much space as you can free up for RAM usage vs. Storage

6. Turn off Windows Hibernation

Windows hibernation background services can use a large amount of system resources. If you don’t use the Hibernate feature on a regular basis you may want to disable it to give Vista a performance boost.
To disable Hibernation:

• Select the Control Panel then Power Options
• Click Change Plan Settings
• Click on Change Advanced Power Settings
• Expand the Sleep selection
• Expand the Hibernate After selection
• Crank the selector down to zero
• Click Apply

7. Turn off System Restore

Analysis and restore point creation by Windows Vista can eat a fair amount of system resources. Disabling this service will obviously mean the system restore feature in Vista will not be available in the event of a system crash. Change this at your own risk.

• Control Panel>System
• Click System Protection on the left panel
• Uncheck the main system drive
• Agree to the confirmation

8. Disable User Access Control (UAC)

This much-loathed new Vista feature attempts to protect your system from malware infection by making you manually confirm a whole host of everyday user operations. While it doesn’t directly impact performance, it can be annoying and might be more hassle than good.
To disable User Access Control:

• Click Start then Control Panel
• Select User Accounts
• Select Turn User Account Control on or off
• Uncheck User Account Control Box
• Restart as recommended

 

9. Disable excess Windows Services that Auto-Launch at Startup

Just like Windows XP, Vista ships with all kinds of services enabled that load at startup and may never be used by most users.
To see what loads at startup and disable the ones you likely won’t be needing (they can always be started manually later):

• Click Start then Control Panel
• Select Administrative Tools
• Choose System Configuration
• Click the Services Tab
• You can safely deselect:
  • Offline Files (unless you’re using Offline File Sync)
  • Tablet PC Input Service (unless you have a tablet PC)
  • Terminal Services
  • Windows Search (If you have already disabled indexing)
  • Fax (unless you’re using a fax modem)

10. Disable Excess Windows Features

Windows ships with other features that are listed separately in the Vista operating system from the startup services.
You can view and disable these features by:

• Clicking Start then Control Panel
• Select Program Features
• On the left panel, select Turn Windows Features on or off
• You can safely deselect:
  • Indexing Service
  • Remote Differential Compression
  • Tablet PC Optional Components
  • Windows DFS Replication Service
  • Windows Fax & Scan (unless you use a modem for faxing)
  • Windows Meeting Space (unless you use the Live Meeting Service)

Well-Known TCP Port Numbers

 

In TCP/IP and UDP networks, a port is an endpoint to a logical connection and the way a client program specifies a specific server program on a computer in a network. Some ports have numbers that are pre assigned to them by the IANA, and these are known as well-known ports (specified in RFC 1700). Port numbers range from 0 to 65536, but only ports numbers 0 to 1024 are reserved for privileged services and designated as well-known ports. This list of well-known port numbers specifies the port used by the server process as its contact port.
